General Description

The NS32081 Floating-Point Unit functions as a slave processor

in National Semiconductor’s Series 32000é microprocessor

family. It provides a high-speed floating-point instruction

set for any Series 32000 family CPU, while remaining

architecturally consistent with the full two-address architecture

and powerful addressing modes of the Series 32000

micro-processor family.
